‹ Overview
The target applications for this function are on equipment that must stop in specific positions including tool changing for
machine tool spindles and die changing for punch/stamping presses. This software also provides for high frequency
operation with automatic switchover to closed-loop operation at low speed.
‹ Applicable Models
This Spindle Orient software is available for the drive models listed in Table 1 .
Table 1 Applicable Models
‹ Basic Concepts and Principles
This orientation software allows an A1000 drive to repeatedly stop a machine at a certain point in its rotational cycle. This
is accomplished by means of an orientation encoder directly coupled to the machine part to be positioned. A simple
example is to think of the hands on a clock. If the orientation encoder is mounted to the motor shaft, this software can stop
the motor so that the spindle stops at the 3 o'clock position every time. Application configurations are outlined in
Figure 1 . For configurations other than those outlined, contact Yaskawa Application Engineering before applying this
software.
